AUTOMATIC UNLOADER FOR TIMBER-IPILING MACHINES.

Specification of Letters Patent.

' Patented Dec. 16, 1919.

Application filed November 4,1918. Serial No. 261,117;

To all whom it may concern:

Be it known that we, JAMES O. BRADNEY and HENRY PRIEsTnR, citizens of the United States of America, residing at Middletown,

in the county of Orange and State of New York, have invented certain new and useful Improvements in Automatic Unloaders for Tii'nber-Piling Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in automatic unloaders for timber piling machines.

The primary object of the invention is the provision of an automaticunloading device for machines of the type set forth in the Hilke Patent No. 1,053,391 and in which the ties or timbers being piled by the ma chine move downwardly toward the deposit or discharge point, our device being adapted for positioning at any desired elevation upon the discharge side of the piler for antomatically removing the ties or timbers therefrom and transferring the same to a pile being formed adjacent the side of the machine.

A further object of the invention is to provide ready means for unloading rimbers and ties from a pilingelevator aru'l arranged for vertical adjustment as the formation of the pile increases in height, arrangement being made for lnaintainingthe unloader horizontal during the operation of the device and while the top layer or tier of the pile is always slightly inclined.

A still further object of the device is to provide in connection with a timber piler having slightly inclined sides, an automatic unloader for the articles elevated by the piler arranged with an automatic follower or gage for maintaining the adjacent side or" the pile vertical and providing a ready means for building up the pile to an altitude adjacent the top of the piler.

It will be understood. that the form of piler herein referred to includes a substantially vertical tower having a loading side for timber and the like adapted for receiving the timbers which are then elevated and lowered upon the opposite side of the tower, which is the unloading side. An automatic loader for such a piler has been fully set forth and claimed in our companion application upon auton'iatic loaders for tie and timber piler, Serial No. 261,116, filed November et, 1918, while our invention set forth herein comprises an automatic unloader for the timber at the opposite or unloading side of the tower. The piler is adapted .Eor bodily movement to the place of piling and the downwardly moving timbers are taken off of the piler by our unloader and fed to a point laterally oi the piler for forming a stack or pile by the person in charge, the timbers being automatically fed to the stack continuously during the operation of the piler, means being. provided upon the piler for vertically adjusting the unloader during the piling operation. The vertical adjustment of the unloader is controlled at either end of the piler, being operated independent from the timber elevating mechanism and the unloader being serviceable for quickly piling large numbers of timbers in piles of uniform size, the unloader being designed for arrangement coinpactlyiolded against the adjacent side of the piler when not in use.

It is also an object of our invention to provide a telescoping unloader adjustable in length-upon the pile of timber being formed thereby so that the discharge end of the unloader may be moved across the pile during the unloading operation, It is further designed to provide the unloader with automatic means for imparting a suitable impulse to thetimber for moving the same over the unloader onto the stackwhile means are also'arranged for normally maintaining the unloader at a fixed inclination when swung downwardly at its lowest inclination while suitable means are provided for retaining the unloader iii-its collapsed arrangement when desired forfolding the same. p

With these general 1 objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereina tter more fully described, illustrated in the accompanying drawings, and then claimed. 7

Our invention relates to an automatic unloader for a timber piler, the general construction of which may be noted by reference'to the aforementioned Hilke patent, only those portions of such piler being herein illustrated as are required for a complete understanding of our unloader. The piler 10 comprises a. tower 11 having I-beam side members 12 slightly converging upwardly to the semicircular top piece 13 of the piler, draft chains 14 being mounted for longitudinally traveling upon the outer flanges 15 of the beams 12. Sprocket wheels 16 are arranged in the top pieces 13 with chains 14 passing thereover while a sprocket chain 17 is arranged within the tower 11 suitably propelled and .controlled at the lower end of the tower for operating the wheels 16 and chains 14.

Brackets 18 are carried by the chains 14 having frames 19 between which a timber or tie 20 is positioned when being conveyed by the piler, in a direction such as downwardly upon the unloading side of the tower 11 as shown in Figs. 1 and 6 of the drawings. Our unloader broadly consists of a table 21 arranged upon the unloading side of the tower 11 and including a mounting frame comprising upper and lower channel bars 23 and 24 respectively provided adjacent each end with a pair of substantially triangular brackets 25. A transverse shaft 28 is journaled through hubs 27 provided upon the brackets while telescoping sine sections 28 of the table 21 are journaled upon the shaft 26 between the brackets 25 of each pair thereof by means of the innermost tubular members 29 of the said side sections.

A brace 30 is arranged transversely of the table 21 connected between the forward ends of the members 29 thereof as at 31 while stays 32 are diagonally arranged connecting a pipe 26 mounted upon the shaft 26 with the said brace 30 as illustrated in Fig. 3 of the drawings. Tubular intermediate telescoping members 33 and 34 are provided for the side sections 28 being arranged in telescoping relations and slidably positioned within the said inner members 29, while outermost members 35 are telescopically positioned within the intermediate members 34. A front brace 36 is provided for the table 21 connected between the forward ends of the side members 35, while similar braces 37 and 38 are arranged transversely of the table 21 connected between the forward ends of the side members 33 and 34 respectively.

rfshaft 39 is journaled beneath the brace 36 in suitable lugs 40 and is arranged with an operating handle 41. Adjustable depend ing shoes 42 are arranged adjacent the opposite ends of the brace 36 slidably positioned within mounting frames 43, a lug 44- being arranged upon each shoe 42 for limiting the downward movement of the shoe while teeth 45 are also provided upon the shoe. A pawl 46 is provided for each shoe 42 being secured to the shaft 39 for normally engaging theteeth 45 of the said shoes, it being noted that when the handle 41 is moved upwardly and forwardly, the pawls 46 will release the shoes 42 so that the shoes may drop downwardly by their own weight upon the pile of timbers therebeneath. lVhen the table 21 is lowered for resting the shoes 42 upon the ties such as 47 as shown in Figs. 1 and 7 of the drawings and during the stacking operation, the table 21 will be held level by the operator with the pawls 46 released until the shoes 42 slidably move automatically into contact with the ties and upon releasing the handle 41, the pawls 46 will engage the teeth 45 retaining the table with the forward brace 36 thereof horizontal.

A hook 48 is pivoted upon arms 49 carried by the brace 38 adapted for engaging either of the braces 30, 37 or 38 during the telescoping of the table 24, a heel 50 being provided for the hook 48 positioned beneath tne brace 36 for limiting the swinging movement of the hook. When the table 21 is fully collapsed, the hook 48 will be engaged beneath the brace 30 thereby holding the table in its closed arrangement, it only being necessary to push the sections together whereupon the hook 48 automatically engages the said brace 30, due to the weight of the heel 50 thereof. The securing of the table closed in this manner prevents the same from opening during the passing of ties thereover when the table is closed.

The frame 22 is vertically shiftably mounted upon the sides 12 by means of brackets 51 and 52 carried by. theopposite ends of the channel bars 23 and 24 respectively. Rollers 53 are provided for the brackets .51 traveling upon the adjacent inner flanges 54 of the inner sides ofthe I- beams 12 while similar rollers 55 of the brackets 52 travel upon the opposite sides of the said flanges 54 as best illustrated in Fig. 2 of the drawings. It will be understood that the weight of the unloader maintains the rollers 53 and 55 in closed engagement with the flanges 54. A hoisting rope 56 is provided for vertically adjusting the unloader and has its central portion'positioned upon pulleys 57 mounted in brackets 58 upon the top of the frame brace 23. The

rope 56 passes over sheaves 59 arranged adjacent the top of the tower 11', thence passing downwardly to any desirable form of adjustable winding means, not shown, suitably controlled in any desired manner by the operator, preferably at points adjacent either side of the piler 10.

The outer forward member 35 of each side section 28 is arranged with a side plate 60 adapted for engaging a similar plate 61 at the outer end of the member 34 and whereby the inner member 35 is prevented from being withdrawn from the inclosing member 34. In a similar manner, the section 34 has plate 62 at its inner end adapted for engaging a plate 63 within the outer end of the side member 33 and preventing the withdrawal of the section 34. The adjacent edges 64 of the pairs of. cotiperating plates 62, 63 and 60, 61 are correspondingly beveled.

The member 29 has its free end portion cut away as at 65 at the top and bottom of the member 29 and arranged with plates 66 secured therein. The section 33 is arranged with an axle 67 positioned through the rear end thereof with tapered cylindrical heads 68 upon its opposite ends laterally projecting from the sides of the section member 33 and permitting the free telescoping movemeni; of the member 33 within the member 29 but preventing the withdrawal of the section therefrom by the engagement of said heads 68 with the inner beveled curved ends 69 of the plates 66. A collar 7 O is arranged upon the axle 67 for retaining the axle in the member 33 while a set screw 71 retains the collar upon the axle. The cut away lower ends 65 of the member 29 permit the section 33 to swing in an arcuate path vertically to an angle of approximately 45 when the section 33 is extended with the pin heads 68-engaging as stops the ends 69 of the plates 66. The-rear end of the sides of the section 33 are rounded at top and bottomas at 72 for riding upon the top and bottom of the outer section member 29 during the swinging movement of the section 33 therein.

The section members 29 are provided upon their opposite sides with longitudinaltracks or ledges 73 upon which substantially triangular plates 74 are adapted to travel by means of suitable wheels 75. A piling gage in the form of a pendant 76 is swingingly mounted between the plates 7 4 by means of a rod 77 connecting. the lower end portions of the said plates and extending through a longitudinal slot 7 8 of the pendant. In this manner, the pendant is swingingly sus pended from the plates 74 it being noted that blocks 79 are arranged between the plates as well as connecting bolts 80.

A toothed portion 81 in the form of a rack is arranged on the underside of each section member 29 while the adjacent pendant 76 is arranged with a spring pressed latch 82 adapted for engaging the teeth 81 during the travel of the pendant 76 toward the free end. of the section 29 when the plates 7 4 travel downwardly upon the tracks 73. By this arrangement the pendants 76 at the opposite sides of the table 21 are free to swing outwardly and away from the piler 10 but are prevented by the latches 82 from traveling inwardly toward the piler. l/Vhen the pile of timbers 47 is started from the ground, the gage pendant 76 is pulled back upon the tracks 73 adjacent the piler 10 and may be locked in position by means of a thumb screw 83. When the pile increases in height the screws 83. are released permitting the pendant 76 to travel downwardly upon the tracks 73 automatically engaging the side of the pile and arranged with a straight vertical edge in. contact therewith. As the height of the pile of ties increases, the unloader is elevated in a step by step movement by means of the ropes 56 and by reason'ofthe slant of the tower 11, the pendants 7 6 slowly travel down the tracks 73 away from the piler and constantly maintain their positions in a true vertical line, it being understood that the latches 82 prevent any return inward movement of thependant gages 76. A projecting pin 84 is carried by each latch 82 extending through a side slot 85 in'the pendant and permitting the retraction of the latch 82 from the teeth 81 when desired for manually moving the pendants 76 toward the piler 10. The mounting of the pendants 76 upon the rods 77 permits the pendants to be swung into engagement with the adjacent sides of the section members 29 ofthe table 21 when the latter is swung upwarlly against the piler 10 in its inoperative arrangement as indicated by dottedlines. in Fig. 1 of the drawings.

shaft 26,the section members 29 are arranged with substantially triangular heels 85 at their rear ends having pads 86 at their" upper ends or apeXes, which pads are 'adapted to rest against cooperating pads 87 castin the brackets 25.

These pads 86 and 87 limit the downward swinging movement of the distributing table 21 but allow freedom of movement toward a level plane as well as during the upward" folding 'movement of the table to its in-' operative position against the piler 10. Au-

tomatic: kickers 88' in the form of curved arms having toothed upper: sides 89i are journaled upon the shaft 26 adjacent to and inwardly of the brackets 25 and are suitably weighted for maintaining the said kickers in their operative upright positions as best shown in Figs. 1, 2, and 3 of the drawings; During the downward movement of a tie 47 upon the brackets 19 of the piler, the descending tie will come in contact with the toothed portions 89 of the kickers, which will swing the latter outwardly unloading the tie from the carriers, the said brackets 19 freely passing downwardly at opposite sides of the holder brackets 25. pending lower portion 90' of each kicker 88 automatically returns the kicker to its vertical position after depositing a tie upon the table 21 and in readiness to receivea subsequent descending tie.

The side sections 28 of the table 21 are essentially of the telescopic arrangement and are herein shown rectangular in cross section. the same being easily manufactured in that form but it will be understood that the members of the sections may be of diflertable 21 is substantially inverted in-the manent form if desired such as cylindrical tubes.- The complete operation of the device will be understood from the foregoing detailed description thereof, it being seen by referring to Fi 1 that an operator positioned upon the pile of ties 47 may receive successive ties for forming a top row or tier and maypartially collapse the table 21 by pushing inwardly upon the outer cross brace 36 thereof and causing the members of the side sections of the table to shorten by their inclination toward the pile being formed during the operation of the deviceand is The deseamen "readily-"adjustable for the formation of a pileof ties or .itimbers reaching from the ground to substantially the "top of the tower 11. :The'arrangement is such-thatrthe kickers 88 insure the forcible deliveryof the ties from the 'piler onto the distributing. table 21 iwhileeither operationrequires no attention,

being entirely automatic and this is alsotrue respecting the piling gages 76 whichare carried by the/table of the unloader.

The kickers'88 heretofore fully described operat to prevent the descending timber, such'as 20, from.beingxengagedzby the upiper fra1nes 19 of: the carrying brackets 18 iduring the operation of-the device and this is 'by reason of-thefact thatwthekickers 88 "receive the timber from the lower frames 19 ofthe 'carryingbrackets 18; such movements bielng automatically accomplished by the weight ofthe descendingtimber. The pipe 26heretofore referred to mounted'upon the shaft 26 is in the nature of-a spacer between the said kickers 88.

The pendant gage 76 may be swung upon -=the shaft 77 to aiposition substantially parallel With-the adjacent'side member 29-"for sliding longitudinally upon the shaft 77 inwardly toward the frame 22. This movement of the pendant 76 brings the stops 7 9 of the plate 7iintocontact-with one side of i the pendant for retaining the pendant alongside of the section-member 29 when the table 21 is in its upraised inoperative position. It will be seen that byswinging the 'table upwardly upon its pivot shaft 26" into contact with the adjacent side of the tower 11 that the pendants 7 6.will=assume their folded positions automatically by swinging inwardly toward the side members 29 and sliding downwardly upon the shaft 76 when the ner set forth.

' 'lWhile the form of theinventio-nherein shown'and described is what is believed to be the preferred embodimentthereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts-may be made without departing from the spirit and scope of the invention as claimed.
